Say you were to attempt to travel between multiple universes. Perhaps by traveling back in, and subsequently altering time, thereby causing you to exist in a universe parallel to your origin (as is stated in one theory). Now, it is generally accepted as a law that matter cannot be created or destroyed. Therefore, the total amount of matter in the universe must be a constant. But if you were to travel between multiverses, you would be reducing the amount of matter in your origin universe and increasing it in your destination universe. My question is, how would this be possible? Does the law of conservation consider all possibly existing universes, therefore negating any issues caused by travel between them?

I image that local conservation of energy to be violated and we we see matter appearing and disappearing.

I don't see how anyone could know anything about how to answer these questions....

Playground

by Mark Beal

 

I wake up in a new universe every day

the old one that was is gone away

but the matter that I occupy seems the same

but I know that it is slowly slipping away

and that the time will come for it to decay

the lucky will find a new home I pray

for it's very nice to have

a healthy place to play

even though it's kind of strange

to be alive in the playground of time

 

 

 

I think we're along ways away from leaving our universe or traveling back and forth in time. We're not even allowed to leave our own back yard. Funny how we all gather around the fence and wrap our little fingers around the chain links and peer out at the neighborhood, and wonder, what's out there, and what's possible.

I guess we can never truly answer any question like this, but there are many things we can learn by observing our universe and creating rules and equations that let us try to discover the truth about the unknown. Much of what we know, or think we know, is simply speculation based on what we already have confirmed.
